GRAIN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 372,340, dated November 1, 1887.

I Application filed August 3, 1886. Serial No. 209,919. (No model.)

To all whom it may concern;

Be it known that we, JOHN F. STEWARD, HERMAN N. KENNEnY,aud Bonn A. KEN- NEDY, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain- Harvesters, which are fully set forth in the following specifica tion, reference being had to the accompanying drawings, forming a part thereof.

This invention consists ofimprovements on the frame work of the grain harvester for whichv there is now pending in the Patent Office our joint application, filed October 19, 1885, Serial No. 180,261.

In thedrawings, Figure l is a front tion of portions of the harvester and binder frames, parts not needed to illustrate the improvements being omitted or broken away. Fig. 2 is a perspective view from the rear outer quarter of portions of the frame containing our improvements. Fig. 3 is a detail perspective of one of the corners of the frame, showing the mode of securing the uprights. Fig. 4 is a perspective view from the front, looking grainward, of the divider-truss and its connection with the finger-bar. Fig. 5 is a stubble-side elevation of the dividertruss. Fig. 6 is a perspective of the post which forms the strut of the divider-truss, the same being shown in connection with a portion of the finger-bar to which it is secured. Fig. 7 is a plan of the divider-truss and its several braces.

A, B, and C are respectively the outer, middle, and inner trusses.

A A are respectively the front and rear outer posts.

B is the forward inner post.

0 is the rear inner post.

The posts A A are secured to the upper bar of the outer truss, A. The post B is secured to the forward end of the upper bar of the middle truss, B. The post 0 is secured to the rear sill, S.

elevanected also to the binder-frame at Z.

The posts A, A213, and C are bent at the upper part to form the horizontal portions A A, 13", and C. To the horizontal portions A A the slide-bearing bars D D are bolted. Said slide-bearing bars are further bolted to the upright portion of the post 0 and to the horizontal portion B of the post C. The sheath-plates F F are secured by being bound between the slide-bearing bars and said posts.

The horizontal parts B 0 of the posts B and C are substantially at the same level and extend grainward beyond the elevator, and

have bolted upon them the seat-plank P. Substantially this structure is claimed in the pending application filed October 19, 1885, Serial No. 180, 261, and therefore is not claimed herein.

The mode of securing the posts to the trussbars is shown in Fig. 3, the upper truss-bars, a b 0', being of angle-iron. The posts are lapped and bolted onto the vertical flanges a 22 0 of said angle-irons, respectively.

H is an arm or bar of ,the binder-frame, which is furnished with bearings on the main frame, in which it may slide when the binder is adjusted back and forward. One of said bearings is the bracket J, which is secured to the top crossbar, I,which is bolted to the posts A A near their bend. The other bearing of the bar H is formed at J in the bracket J, which is rigidly secured (as by the bolt j) to the post A at its bend. At the inner end of the horizontal part A there is secured the bracket J which comprises the notched sector J and the bearing J. In the latter is journaled the rock-shaft K, which has another bearing at J in the bracket J, and outside the latter is bent to form the crank-arm K, to which is connected the link L, which is con- At the inner end the rock-shaft K has the lever-arm Kflvibrating past the notched segment J",and provided with suitable means for locking it thereto. Said lever-arm K and the rock-shaft K and its connections thus serve the purpose of adjusting the binder back and forward on the harvester.

Upon the horizontal part B of the post B are secured the small brackets M M, in which isjournaled the rock-shaft M, which has at one end the crank-arm hi and at the other end the lever arm or handle M, the latter extending up past the notched segment N, which is fixed as a bracket upon the forward portion of the scat-plank. From the crank-arm M the link M extends to the tongue, to which it is connected at m The lever-arm M is there fore that by which the tilt or inclination of the platform is adjusted, commonly called the tilting-lever.

R is the divider-trussthat is to say, the truss which forms the grain end of the platform-frame and carries the divider. It consists of the upper and lower bars, R and It", both made of angle-iron,connected at the rear by the clip or clasp R, which grasps the tubular rear sill, S, the bracket or post R, and the grain-wheel guide-post It. The upper and lower bars, 1t and B diverge from their connection with the rearsill to their junction with said post, and the latter, having the lugs R and R, forming shoulders over and under which the said bars R and R respectively bear, forms a strut for the truss. From said post the bars R and R converge forward and are united at the point of the divider. The post It, below the shoulder R", is expanded to form the feet It, and to said foot is secured the finger-bar T, which also forms a front sill of the platform. Said finger-bar is formed of Z-iron, thelower horizontal flange of which atfords the opportunity of securing it to the foot R, while, the vertical web of said Z-iron abutting against the forward side of the foot, said foot It is firmly braced thereby. Above the shoulder R the post R has the upward extension R", and to the upper oblique head or sole It of said extension is secured the divider-board R, which, extending obliquely downward and forward and being sharpened toward the forward end,makes a junction with the forward ends of the upper and lower bars, R and R".

From the point where the truss-bars cross the linger-bar said truss-bars are bent grainward, so that their vertical plane makes an obtuse angle with the vertical plane of the finger-bar and an acute angle with the line of travel, whereby they gather the grain to the sickle.

To the end of finger-bar, which projects slightly beyond the grain edge of the post It, is secured the brace r, and the guard R which is fastened at the rear end to the sill S and at the forward end makes a junction with the upper and lower frame-bars, is intermediately bowed grainward and held in that position by the brace 1', which is bolted to it at the end. The common junction of the forward ends of the bars It and It", the board R, and the brace R is covered by the prow r.

The grain-wheel post R is located considerably rearward of the post It and provided with the lugs R two projecting above the lower bar, and two projecting below the upper bar, R, of the truss, and thereby said post is made to serve as an additional strut for the truss. The same belt which secures the upper bar, It, to the post It also takes through the brace R which is rigidly secured both to the post and to the bar. The belt which secures the lower bar, It", to the grainwheel post It at the lower forward lug, B also takes through said brace at its rear end, and thereby secures it rigidly both to the lower bar and to the grain-wheel post.

Considering now the portion R of the bar R from the post R forward to the prow and that portion R of the bar 1% from the post R forward to the prow and the brace It", it will be seen that they constitute a truss independently of the remaining portions of the bars It and R", and that of said truss the post It forms a strut.

Considering the portion R of the bar R from the junction with the post R rearward to the rear sill and the portion R of the bar R from the junction with the post R rearward to the rear sill and the brace It, it will be apparent that said parts form a truss of which the post RE is a strut.

The belt which secures the upperbar, R, to the grain-wheel post R" at the lug R also takes through the brace R", which is thus rigidly sceured both to the post and to the bar, and extends thence to the extreme grain end of the finger-bar T, to which it is secured a few inches grainward from the intersection of the vertical plane of the truss to the fingerbar.

For-the purpose of analyzing the structure to understand how it is braced, the junction of the finger-bar to the post may be treated as coincident with that of the post to the fingerbar. A line in the vertical plane of the truss from such coincident junctions to the lug R forms the longer leg of a rightaugled triangle, of which the shorter leg is a distance grainward on the finger-bar from its junction with the truss to the fastening-brace It", and the said brace forms the hypotenuse of such triangle, and tends, therefore, to prevent the truss and grainwvheel from being laterally distorted.

Considering the portion of the upper bar, It, from the post R" rearward, the portion R of the lower bar, R, and the brace R treated as if connected at its forward end to the bar R as it is substantially, by means of the extension T of the finger-bar and the foot R of the post It", it will be apparent that said parts constitute a truss, of which the post R is a strut.

By these several braces making the divider frame-work consist of interlaced trusses, the divider is made very stiff and the platformframe and the grain-wheel are kept very firmly in proper relation.

\Ve claim 1. In combination with the post A and the brackets J 2 and J, rigidly secured thereto, the latter having the slide-bearing J for the binder-frame, the rock-shaft K, journaled in said brackets J and J and having the crankarm to actuate the binder, substantially as set forth.

2. In combination with the trusses having their upper bars-formed of angle-iron, the

posts bolted to the vertical flange of such angle-iron truss-bars, substantially as set forth.

3. In combination .with the finger-bar and the upper and lower bars of the divider-truss, a post, as R, footed on the finger-bar, and having lugs forming shoulders to spread the truss-bars and adapt the post to form the strut of the truss.

4. In combination with the lower-bar, R, the portion R of the upperbar, and the brace R the post R constituting a strut for a truss formed by the other parts named, substantially as set forth.

5. In combination with the portion R of the upper bar, the portion R of the lower bar, and the brace R, thepost R constituting a strutfor the truss formed by the other parts named, substantially as set forth.

6. In combination with the divider-truss, the finger-bar, rigid with the lower bar and extending grainward beyond it, and the brace B", secured to the upper bar and to the grainward extension of the fin ger-bar, substantially as set forth.

7. In a harvesting-machine, a trussed frame which, as a unitary structure, constitutes both the grain end of the platform and the divider, and having metal upper and lower bars, that portion of said frame which extends between the two sills being parallel with the line of travel. and its said bars being deflected grainward forward of the front sill to cause the divider portion to operate as a gatherer, in combination with a bar, as R connected to the lower bar of said trussed frame forward of and rearward of the front sill, and a brace extending from the sill grainward to such bar, whereby the said bar and the lower barvof such trussed frame, with the brace, constitute a horizontal truss to stiffen said frame laterally, substantially as set forth.

In testimony whereof we have set our hands this 27th day of July, 1886-, in. the presence of two witnesses, at Chicago, Illinois.
